Abstract

【課題】ＬＥＤのような光の指向性が強い光源を用いた厚さの薄いライトボックスや、ＬＥＤの数を従来の１／４～１／９に減らした場合にも、表面照度にムラが発生することが抑制されるライトボックスを提供する。 【解決手段】複数の点状光源４と、光反射板２１とを具備し、光反射板２１は、点状光源４のそれぞれを取り囲む収納凹部２２を有し、この収納凹部２２の底部に形成された挿通孔２３に点状光源がそれぞれ挿通されており、点状光源４から出射される光の入射角が０°であって３５０ｍｍの距離をおいた場合の輝度が１５０００ｃｄ／ｍ２以下であり、点状光源４から出射される光の一部または全部が収納凹部２２の内面で反射してから照明に供するライトボックス１とする。
